Why must be centered when hot-rolled thick-walled seamless hot rolling seamless pipe mill

To know why the tube blank must be centered when hot-rolling thick-walled seamless steel pipes, we must first know what is the centering of the tube blank? In order to align the nose of the hot-rolled seamless steel pipe with the front end of the tube blank during piercing, a shallow circular hole is processed at the front end of the tube blank before the tube blank is pierced.What is hot rolled seamless steel pipe - www.ugsteelmill hot rolling seamless pipe millHot-rolled seamless steel pipe is generally produced on automatic rolling mill units. The solid bar is inspected and cleared of surface defects. Then it is cut into the required length, and centered on face of the perforation end of the pipe billet. And then it will be sent to the heating furnace to heat, and bore a hole on the puncher.Used Seamless Pipe Mill for sale.
